Embodiment Construction

[0048] In the following, only certain exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, and different embodiments may be combined in any way without departing from the spirit or scope of the present disclosure, all without departing from the spirit or scope of the present disclosure . Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0049] In the related art, for medium and large-sized OLED products, an out-cell touch method can be used to increase the distance between the Tx line and the cathode, and the distance between the Rx line and the cathode, and further Reduce the touch capacitance to ensure that the product RC between the capacitance and the resistance is a small value. However, the use of the external touch method leads to an increase in the thickness of the module and an increase in the bending rad...

Abstract

The embodiment of the invention provides a touch panel and a display device. The touch panel includes: a display substrate; the conducting layer is located on one side of the display substrate, and a plurality of hollows are formed in the conducting layer; the packaging layer is located on the side, away from the display substrate, of the conductive layer; the touch control structure layer is located on the side, away from the display substrate, of the packaging layer, the touch control structure layer comprises a plurality of touch control wires, at least one touch control wire corresponds to at least one hollowed-out part, and the orthographic projection of the touch control wire on the display substrate and the orthographic projection of the corresponding hollowed-out part on the display substrate at least partially coincide. According to the technical scheme, the relative area of the touch wires and the conducting layer is reduced, stray capacitance between the touch wires and the conducting layer is reduced, the product RC of capacitance and resistance can be kept small, the load of the touch panel is reduced, the charging and discharging time of the touch electrodes is shortened, and the touch performance is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a touch panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is a display lighting technology that has gradually developed in recent years. Especially in the display industry, OLED displays are regarded as possessing the advantages of high response, high contrast and flexibility. Broad application prospects. [0003] With the gradual expansion of OLED products from the mobile phone business to medium and large-sized businesses such as tablet computers, notebooks, and vehicles, the size of the display screen continues to increase. For mid-to-high-end mobile phones such as mobile phones, the touch function of the OLED screen adopts an on-cell design, which makes the screen thinner and lighter, especially in folding mobile phones. On-cell design is widely used. For medium and large size terminals, the screen size is larger, t...
